Performance optimizations, changes in these areas:
  - RX and TX checksum offload
  - correct maximum MTU
  - don't use TX interrupts anymore, use a timer instead
  - remove some superfluous barriers
  - improve RX RAM full handling

The driver incorrectly used dma_addr_t to describe
HW structures and consequently broke when that type
was changed in 2.6.15-rc.

This changed spidernet to use u32 for 32 bit HW defined
structure elements.

request_firmware() is sometimes problematic, especially
in initramfs, reading the firmware from Open Firmware
is much preferrable.

We still try to get the firmware from the file system
first, in order to support old SLOF releases and to allow
updates of the spidernet firmware without reflashing
the system.

Uploading the device firmware may fail if wrong input data
was provided by the user. This checks for the condition.

This patch makes the driver work with any BladeCenter
network switch, it used to work only with certain
models.

This patch adds a driver for a new 1000 Mbit ethernet NIC.  It is
integrated on the south bridge that is used for our Cell Blades.

The code gets the MAC address from the Open Firmware device tree, so it
won't compile on platforms other than ppc64.

This is the first public release, so I don't expect the first version to
get merged, but I'd aim for integration within the 2.6.13 time frame.
